A net of a square pyramid is shown below. What is the surface area, in squared centimeters, of the pyramid?
A. 60.7
B. 86.7
C. 121.4
D. 147.4
Answers
Answer:
[tex]\text{B. }86.7}[/tex]
Step-by-step explanation:
The total surface area of the square pyramid consists of one square and four congruent triangles. By adding the total area of each, we get the total surface area of the square pyramid.
Area of the square: [tex]5.1^2=26.01[/tex]
Area of four triangles: [tex]4\cdot \frac{1}{2}\cdot 5.95\cdot 5.1=60.69[/tex]
Therefore, the total surface area of the pyramid is [tex]26.01+60.69=\boxed{\text{B. }86.7}}[/tex]

The surface area of the sphere is 192 cm^2
so the radius is ______ cm
and the volume would be _____ cm^3
Answers
Answer:
radius = 3.91 cm; volume = 250.4 cm^3
Step-by-step explanation:
Since you have everything except the radius, r, divide the surface area, 192 cm^2, to get the radius.
After you’ve done that, take the radius, 3.91, substitute it into the formula for volume.
Formula for volume is = 4/3πr^3

The formula to find out the volume of a rectangular prism is V = l × b × h where V is the volume , l = length , b = breadth & h = height.We're provided the figure of trapezium in the second attachment. The formula to fInd out the area of trapezium is A = [tex] \tt{ \frac{1}{2} h(a + b)}[/tex] where a and b are the opposite parallel sides and h be the height of a trapezium.[tex] \large{ \tt{❃ \: SOLUTION}} : [/tex]
In the first picture , we're provided - Length ( l ) = [tex] \frac{7}{4} [/tex] cm , breadth ( b ) = [tex] \frac{3}{2} [/tex] cm and height ( h ) = [tex] \frac{1}{2} [/tex] cm. Now, plug these known values and them find out the volume of given rectangular prism.[tex] \large{ \tt{❁ \: VOLUME \: OF \: RECTANGULAR \: PRISM \: ( \: V \: ) = l \times b \times h}}[/tex]
[tex] \large{ {⟶ \: \frac{7}{4} \times \frac{3}{2} \times \frac{1}{2} }}[/tex]

The ice cream costs $__ for a small serving and $__ for a large serving.`
Answers
small is $1
Answer:
$24
Step-by-step explanation:
5 large servings = 4 + 4 + 4 + 4 + 4 = $20
4 small servings = 1 + 1 + 1 + 1 = $4
20 + 4 = $24
The ice cream costs $1 for a small serving and $4 for a large serving.

Jezebel took a train to visit her uncle. The train traveled at a constant speed of 40 miles per hour. Complete the table. Then, write an equation to find the total distance d traveled after t hours.
Answers
Answer:
[see below]
Step-by-step explanation:
We can tell that for every hour passed the distance traveled by the train would increase by 40 miles.
We can use the equation d = 40t to determine the values of the table. The 'd' is total distance and 't' is the number of given hours.
Two hours:
d = 40(2)
d = 80
Three Hours:
d = 40(3)
d = 120
Four Hours:
d = 40(4)
d = 160

Let x stand for the number of hours and y for the overall expense.
Company A: y = 25x + 20
company B: y = 20x + 45
To find the number of hours it will take for the cost to be the same for both companies, we need to solve the equation:
25x + 20 = 20x + 45
Simplifying the equation, we get:

Solve the system of equations below by elimination. Write your answer as an ordered pair. e.g. (2,3)
Answers
Answer:
(45,35)
Step-by-step explanation:
1 - Stack the equations on top of each other
3x - 4y = -5
4x + 4y = 40
2 - We can eliminate by subtracting the bottom equation from the top equation
3x - 4y = -5
- 4x - 4y = 40
3 - The y's cancel out, leaving us with...
3x = -5
- 4x = 40
4 - Continue simplifying
-1x = -45
5 - We can switch the -1x with -x to make things simple
-x = -45
6 - Positize (make it positive) the statement
x = 45
7 - Halfway there! Substitute the x value into one of the equations
(3 * 45) - 4y = -5
8 - Solve
135 - 4y = -5
Minus 135 on both sides
-4y = -140
Divide by -4 on both sides
y = 35
9 - Here is your answer!!
x = 45
y = 35
